But as far as I can tell they didn't break any laws, at least not in a black and white manner.
You're comparing two completely different things. One is the actions of individuals whose actions are clearly breaking laws that are written in black and white. The other is actions of a collection of people, who might be acting unethically, but for all intents and purposes are following all the laws and regulations that apply to the businesses responsible for the manufacturing and distributing of legal substances. There is a real chance that no one involved in this whole ordeal was acting maliciously and that the mess we're in is just another result of failing system. You're upset. That's cool. This is something worth being upset about. That doesn't mean though that anyone actually did anything legally wrong, or else this would be a criminal trial, not a lawsuit.
